When replacing a toggle switch, it's good practice to inspect associated electrical components.
Check for corrosion, loose terminals, or damaged insulation; repair as needed.
If the switch failed due to overload, verify the protection device is functioning correctly.
Protective boots keep out moisture and debris; replace if torn or missing.
